While the flash and busts go in the first round of the NFL draft, Super Bowl champions are built in the later rounds. Here are five things to watch during Friday night's second and third rounds:

1. SECOND ROUND SHOULD BE OFFENSIVE

With 18 of the first 32 selection being defensive players, the top talent remaining on the draft board is now heavily leaning toward the offense. With quality receivers such as USC's Marqise Lee, Vanderbilt's Jordan Matthews, Penn State's Allen Robinson and Indiana's Cody Latimer still on the board along with a handful of talented O-linemen, the offensive players should outnumber the defensive players in Round 2 and maybe Round 3, as well.

2. WHEN WILL A RUNNING BACK GO?

The days of running backs dominating the first round of the draft are long gone. This is the second straight draft in which no running backs were selected in the first round. Ohio State's Carlos Hyde, LSU's Jeremy Hill and Washington's Bishop Sankey will be looking to join an NFL franchise in the second round. The Titans (42nd overall) and Giants (43rd) are the most likely teams to target a running back.

3. TOP SECONDARY TALENT RUNNING DRY

With five cornerbacks and four safeties selected in the first 31 picks, teams still looking to get an instant starter in the secondary are in trouble. It is possible that no players from the secondary are drafted on Day 2 until the Indianapolis Colts make their first selection with the 26th pick in the second round. The Colts are looking to replace safety Antoine Bethea, who signed with the San Francisco 49ers during free agency. If Indianapolis still had its first-round pick (sent to Cleveland for running back Trent Richardson last season), the Colts would have been able to grab Deone Bucannon, who was selected by the Cardinals at No. 27, or Jimmie Ward, who the 49ers nabbed with the 30th pick.

4. MORE TRADES IN THE WIND

When the Minnesota Vikings jumped up to get the final pick of the first round and grab Louisville quarterback Teddy Bridgewater, it marked the eighth trade of the draft's first night.

If the Houston Texans don't select a quarterback with the first pick of the second round, expect rumors to get hot and heavy that New England Patriots' 6-foot-7 backup Ryan Mallett could be headed to the Texans for a draft pick. That talk is likely a lot of hot air as a deal for Mallett is much more complex than most trades that would be completed in the midst of a draft. But after the draft ...

One quarterback who could be easier to make a draft deal for is former Minnesota Vikings first-rounder Christian Ponder. Finding a team willing to give up a pick for Ponder, who has 38 touchdowns and 34 interceptions in his NFL career, will be an interesting trick.

5. WHO STILL NEEDS A QUARTERBACK?

Fresno State's Derek Carr, Eastern Illinois' Jimmy Garappolo, LSU's Zach Mettenberger, Alabama's AJ McCarron and Pittsburgh's Tom Savage were talked about as possible second- or third-rounders. So who could use a quarterback?

The Texans (No. 33 overall pick), Raiders (No. 36), Buccaneers (No. 38), Rams (No. 44) and Cardinals (No. 52) could all be interested in a young signal caller in the Round 2.
